چکیده

Turbo codes are sensitive to both (timing) synchronization errors and signal-to-noise ratio (SNR) mismatch. Since turbo codes are intended to be deployed in environments with very low SNR, conventional synchronization methods often fail. This paper introduces a solution for jointly estimating the SNR and achieving timing synchronization based on the statistics of the received signal. Simulation results show only a small loss in coding gain relative to perfect timing and SNR estimation while requiring only slightly more complexity and latency.

An approach to fault detection and correction in design of systems using of Turbo ‎codes‎

We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...

ML frame synchronization for turbo and LDPC codes

This contribution introduces a novel maximumlikelihood (ML) frame synchronization technique for coded systems that exploits the code properties by accepting soft information from the MAP decoder. Simulation results are presented for turbo and LDPC codes, and are compared to performance results of a frame synchronizer that does not use the code properties. We show that code-aided frame synchroni...

Decoder Assisted Channel Estimation and Frame Synchronization

In regards to turbo codes, to the author's knowledge, previous literature has treated decoder assisted frame synchronization and channel estimation as separate processes. Here a joint decoder assisted process of channel estimation and frame synchronization is proposed. In brief, the method entails using a sync word (SW) embedded mid-packet for both channel estimation and frame synchronization. ...

Timing Synchronization with Turbo Codes on AWGN Chan- nels

This paper presents the behaviour of a turbo coding scheme when the symbol timing is not perfectly known. The algorithm for timing synchronization together with the theoretical Cramer Rao bound and the performance of an NDA ML synchronizer are presented. It is shown that synchronization can be achieved using the soft bit outputs of the turbo decoder without the need of using complex separate sy...

Stream-oriented turbo codes

This work considers the design and performance of a stream-oriented approach to turbo codes which avoids the need for data framing. The stream paradigm applies to both serial and parallel turbo codes using continuous, free-running constituent encoders along with continuous, periodic interleavers. A stream-oriented turbo code based on parallel concatenated convolutional codes (PCCC) is considere...
